描述 Description

The PAM8403H is a 3W, class-D audio amplifier. It offers low THD+N,
allowing it to achieve high quality sound reproduction. The new
filterless architecture allows the device to drive the speaker directly,
requiring no low-pass output filters, thus saving system cost and PCB
area.

With the same numbers of external components, the efficiency of the
PAM8403H is much better than that of class-AB cousins. It can
extend the battery life, ideal for portable applications.

The PAM8403H is available in SOP-16 package.
